This post is off topic from my typical musings.
According to the May issue of Discover Magazine, engineers at MIT have built a shock absorber that can generate energy to help keep a car battery charged.
As the car bounces up and down while moving down the road, the shocks harness the heat that is normally wasted and converts the energy into electricity. This allows the battery to run the air, stereo, and lights with more efficiency. That translates into better gas millage and less pollution.
Zee, I thought that you in particular would get a kick out of this one-- not to exclude anyone else who reads this, of course!
